Another primary night has come and gone, with Democrat Bernie Sanders taking home his 19th win in West Virginia and Republican Donald Trump inching closer to solidifying his nomination. The remaining three presidential candidates are just a few weeks away from the end of primary season and the party conventions in July.

Democrats

Bernie Sanders and rival Hillary Clinton faced off in West Virginia as they vied for 29 delegates. Pre-primary polls showed the Vermont senator ahead of Clinton by single digits, and, despite an early lead by Clinton after polls closed, he managed to clinch a win in the Mountain State. With 88% reporting, Sanders led Clinton by 15.2% and more than 33,000 votes. Although Sanders won, the two split the state's delegates following a proportional system. Sanders won at least 16 delegates, while Clinton took home at least 11. The last two delegates were not allocated by time of publishing.

The two also faced off in a largely symbolic Nebraska primary, of which Clinton won. The two previously competed on 5 March in a Democratic caucus, which Sanders won. The March caucus is counted in terms of delegates. Sanders took home 14 of the state's 25 delegates, while Clinton nabbed 10 delegates.

Despite his victory in West Virginia on Tuesday (10 May, Sanders lags far behind Clinton in delegate count. The former secretary of state leads with 2,239 delegates to Sanders' 1,469 delegates. Democratic candidates need 2,383 delegates to clinch the nomination. An additional 1,057 delegates are still available.

Republicans

Presumptive Republican nominee Donald Trump cruised to victory in West Virginia and Nebraska. Trump, the last GOP nominee, was declared the winner of each race as soon as polling locations closed at 7.30pm EDT/12.30am BST and 9pm EDT/2am BST respectively.

With 88% reporting, Trump won in West Virginia with a whopping 76.6% of the votes. The billionaire real estate magnate received over 100,000 votes more than former rivals Ted Cruz and John Kasich combined. Cruz and Kasich suspended their campaigns on 3 May and 4 May respectively after a devastating loss in Indiana. Trump took home at least three of the Mountain State's 34 delegates. The remaining 31 delegates were not allocated at the time of publishing.

Trump's victory in Nebraska was equally as monumental as his success in West Virginia. With 82% reporting, the former reality TV star took the Cornhusker State with 61.9% of the votes. Trump received more than 55,000 more votes than Cruz and Kasich combined and, ass Nebraska is a winner-take-all state, Trump won all 36 delegates available.

As the only remaining GOP candidate, Trump is now the party's presumptive nominee. He is 130 delegates away from making his nomination official with 1,107 delegates. Republican nominees need 1,237 to clinch the nomination. There are 466 delegates still available.

The three candidates are just a few states away from the end of the primary race. The next primaries will be in Oregon (for both parties) and in Kentucky (for Democrats only) on 17 May.
